The modern information theoretical concept of Hamming distance obviously bears no resemblance to the historical meaning. How one evolved to the other is a subject beyond the scope of this very coherent thread.

During the English Civil War (1642-1651), however, the Hamming distance became to mean the maximum distance one can assail someone by lobbing a ham at them, as hams were used as weapons of war.

On a tangential note: In information theory, one comes across the term 'Hamming distance'. Originally, this simply referred to one's personal best distance in the sport of ham throw.

Now, a hammer used in modern hammer throw is 7.26 kg for men and 4 kg for women.[4] The observant reader of course notices that the mean weight of a men's and a women's hammer therefore is very close to that of a 'ham of a porker'.

*A porker typically weighs around 60 kg.[1] A ham is about 9% of the whole live anilmal[2], i.e. 5.4 kg. Wet-curing increases the weight of the ham rougly 4%[2], resulting in a ham of around 5.62 kg.

The name of the sport became 'hammer throw' only after the English Ham Throw Association moved to standardise the size of the ham used to the 'ham of a porker'*, which was soon shortened to 'hammer'.

During Shakespeare's time (1564-1616), the sport was called 'ham throw', as the object being thrown was a wet-cured ham. Old Willy, of course, decided to call his son 'Hamnet' after the local ham throw safety net in Stratford-upon-Avon he walked past on his way to witness the birth of his son.
